Abstract : This study was conducted to investigate the effectiveness of ethanol extract of mango peel waste for the inhibition of the corrosion of aluminium in solution of HCl using weight loss and gasometric methods. The results obtained indicated that ethanol extract of mango peel waste displayed average inhibition potential for the corrosion of aluminium in solution of HCl. The inhibited corrosion reaction supported a first order kinetic while its adsorption was exothermic , spontaneous and consistent with the mechanism of physiosorption. The adsorption behaviour of the inhibitor was best described by the Langmuir, Temkin, El awardy et al and Dubinin-Raduskevich adsorption models.
